comment even/odd (3 posts)

I use the Kubrick template (for now) and just upgraded to 1.3a 5 from 1.2.1. Smooth transition other than, in my old template, every other comments was styled differently (i.e., had a grey background) thus making it easy to distinguish where one stopped and another started. 1.3a'5' isn't picking up on this change...any ideas (maybe from Ku~ users?) about changing this back?
Also, I'd love to have comments by a certain author (mainly, [only], me) show up w/ a diff color b/g as well....
Thanks in advance for any suggestions....
